Abstract

The utility model discloses an auxiliary guide device used for cutting steel plate curved bevelled edges, comprising a connecting rod which is fixed with a fixed retaining block; one end of the connecting rod is in screw and nut structure and the other end thereof is fixed in a sliding block by a housing pin; the lower part of the sliding block is connected with a vertical shaft; the lower part of the vertical shaft is provided with a thread which is connected with an idler wheel device. The device of the utility model is not restricted by field and is flexible and smart, has no severe restriction to the size of the operation surface, can achieve an expected process requirement by that the size of the surface of the steel plate to be processed leads a half-automatic flame cutting machine to be effectively rotated, and has the advantages of simple and convenient operation, low labour intensity, effort and time saving, slippery and beautiful cut processing surface, high precision and almost no repairing requirement.

Description

A kind ofly cut the auxiliary guide that the steel plate curve slope is used

Technical field

The utility model relates to a kind of flame cutting technique of steel plate processing, relates in particular to a kind of auxiliary guide that the steel plate curve slope is used of cutting.

Background technology

In the steel construction process, through the requirement that regular meeting exists steel plate and steel plate (or other steel) to connect, general type of attachment has bolt or welds two kinds.

In welding, because the requirement of welding procedure, to carry out various forms of groove processing for the position of need welding, see shown in Fig. 1～Fig. 3, this groove type has straight line, circular arc or certain specific smooth curve, among Fig. 4, bevel angle 11 can change between 0～80 °, and root face 12 also has the variation of width.Enterprise with good conditionsi is processed with machine cut or flame cutting dual mode to groove, and this dual mode has higher requirement to equipment more, and equipment investment is required height, needs bigger processing place.

Under common simple machine condition, manual flame cutting or semiautomatic flame cutting machine cutting are arranged for the groove processing method of steel plate.Manual flame cutting labour intensity is big, the difficult quality guarantee of cut surface, and is to adopt the semiautomatic flame cutting machine cutting during most cases:

A kind of is the artificial direction of travel of constantly regulating semiautomatic flame cutting machine, and consistent with the workpiece shape to guarantee otch, this method is more better than hand cut quality, but still labour intensity is big, the difficult quality guarantee of cut surface.

Another kind method preferably is the pattern method, sees Fig. 5, when cutting parts 13 grooves, makes the pattern consistent with the processing work shape 14 earlier, allows semiautomatic flame cutting machine 15 against pattern 14 walkings, and is consistent with the workpiece shape to guarantee cutting profile.As adopting fixedly pattern, the processing capacity of pattern is very big, is unfavorable for reducing construction costs, and carrying pattern trouble, operation inconvenience.As adopt adjustable pattern, and the debugging of pattern is wasted time and energy, and is difficult to transfer very accurately, in case error is excessive, the repairing amount after the processing will strengthen.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple and easy to do, can reduce labour intensity significantly again, and what increase substantially efficiency a kind ofly cuts the auxiliary guide that the steel plate curve slope is used.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind ofly cut the auxiliary guide that the steel plate curve slope is used, it comprises a connecting rod, be fixed with fixed stop on the described connecting rod, one end of described connecting rod is screw rod, nut structure, its other end is fixed in the slide block by holding out against screw, the bottom of described slide block is connected with vertical pivot, and the bottom of described vertical pivot is provided with screw thread and is connected with roller devices thereon.

Adopt the utility model device not limited by the place, flexible, size to the scope of operation does not have harsh restriction, as long as processed steel plate plate face size can make that semiautomatic flame cutting machine effectively turns round, just can carry out our desirable processing request, realized easy and simple to handle, labour intensity is low, saving of work and time, the machined surface that cuts out is smooth, attractive in appearance, the precision height need not be repaired substantially.Example: cutting long 20m, thickness of slab 50mm, 35 ° of bevel angles, root face together is 2mm, during such curve slope, if when operating with adjustable pattern method, need two skilled operators to adjust pattern earlier, one hour time spent, then cut again one hour, just can finish the work.After using this method instead, only need an operative employee, just can finish the work in one hour, and crudy also is better than the former, can save 2/3rds costs of labor.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

A kind of shown in Fig. 1-7 cuts the auxiliary guide that the steel plate curve slope is used, it comprises a connecting rod 1, be fixed with block 2 on the described connecting rod 1, one end of described connecting rod is screw rod, nut structure, its other end is fixed in the slide block 4 by holding out against screw 3, in use fixed stop 2 is adjacent to an end face at cutting machine 9, and the nut 10 on the connecting rod is pressed on cutting machine 9 another end faces.The bottom of described slide block 4 is connected with vertical pivot 5, and the bottom of described vertical pivot is provided with screw thread and is connected with roller devices thereon, and described roller devices preferably is installed in bearing 8 on the described vertical pivot 5 by last lower nut 6,7.

Its operation principle is:

When using the semiautomatic flame cutting machine cutting, allow auxiliary guide wheels nestle up machined surface, do datum level with existing machined surface, the directive wheel that semiautomatic flame cutting machine is advanced is to the direction adjustment away from the scope of operation simultaneously, make it produce the motoricity that will break away from, but because the restriction of auxiliary guide wheels, the movement locus of semiautomatic flame cutting machine reality has been the shape of machined surface just just, thereby has just reached purpose to be processed.To note during practical operation:

(1) directive wheel of semiautomatic flame cutting machine approximately need be regulated 10～15 °, can be according to the curvature of camber line, concavo-convexly determine, and the convex camber line, it is big that angle is wanted; The spill camber line, angle is smaller.

(2) bearing 8 will guarantee closely to paste mutually with the scope of operation that will process; The front-end and back-end of semiautomatic flame cutting machine fuselage will guarantee with machined surface equidistant.

(3) during the crowd shovel groove, slide block is moved forward; During the backhoe groove, slide block can be moved backward.During practical operation, can adjust as the case may be.
